I'm designing a circuit that supplies power via USB to an Arudino. The USB power runs through a 3v3/5v dual regulator. I'd like to use a small tactile switch in front of the IN lead on the regulator as an interrupt/reset apparatus, but I'm finding it difficult to obtain a suitable NC switch, though I have a variety of suitable NO switches on hand.
How reasonable is it to close the switch to ground as a means of interrupting power to the rest of the circuit? As an example:
My assumption is that the resistance of the regulator and everything past it will make the closed-to-ground path better and should interrupt the power. But I've never used an NO switch in this fashion and wanted to make sure I wasn't missing anything.
